The show features interviews with Heidi, Spencer and others who’ve had the terrible misfortune to come into contact with them

It would have been helpful for this one-hour documentary to have been screened BEFORE Celebrity Big Brother, so British viewers would have had a bit more warning about the couple who would put the UK’s “special relationship” with America back about 50 years.

To paraphrase former Big Brother contestant Nikki Grahame: “Who ARE they?! Who ARE they?”

Having met on reality show The Hills, CBB runners-up Heidi Montag and Spencer Pratt have pulled off an astonishing double – they’re the most loathed celebrity couple in the US and here in Britain, too.

This show, featuring interviews with Heidi, Spencer and others who’ve had the terrible misfortune to come into contact with them, reveals the truth (or at least their version of the truth) behind their marriage, the divorce that never happened, Heidi’s Playboy ­photoshoot, her extensive plastic surgery, Spencer’s bankruptcy and much, much more.
